First of all, please check with bug #69115. Recently an issue with mail() was fixed.
Secondly, I see a potential issue in the bt supplied. call_user_func() seems to be called
recursively and that can lead to the stack overflow. PHP has no recursion protection for this case.
Please check the script. If that's the case, there'll be probably no need to share the
dump. Otherwise, please send a mail with the link to the dump.
Thanks.
